Overview
The LB1947-E is a PWM current control type bidirectional DC motor driver IC manufactured by Sanyo. It operates with a load voltage range of 10V to 45V and provides a continuous output current of 2A. The device features selectable current decay patterns, including FAST, SLOW, and MIX DECAY modes, alongside a simultaneous ON prevention function. It utilizes a 13-pin SIP package for through-hole mounting and supports an operating temperature range from -20°C to 85°C.
Feature Summary
- PWM current control with fixed OFF time
- Selectable current decay patterns (FAST, SLOW, MIX)
- Simultaneous ON prevention function
Applications
- General purpose motor driving
- Bidirectional DC motor control systems
Procurement Notes
Verify the specific suffix 'E' against official Sanyo documentation to confirm pinout and electrical specifications match your design requirements. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Cross-reference the 13-pin SIP package dimensions with your PCB footprint before finalizing procurement orders.
Selection Notes
Select this component when bidirectional control of a DC motor is required within a 10V to 45V supply range. The integrated PWM current control and selectable decay modes make it suitable for applications needing precise torque management. Verify that the 2A output current rating meets the peak and continuous load demands of the target motor system.
Part Context
This part belongs to the PMIC Motor Drivers category, specifically designed as a motion controller. It is distinct from generic logic drivers by its integrated power stage and current regulation capabilities. The LB1947 series is engineered for robust performance in industrial and consumer electronics requiring reliable motor actuation.
Replacement Considerations
Check for direct cross-references in official Sanyo replacement guides. Generic equivalents may lack the specific MIX DECAY mode or simultaneous ON prevention features. Verify thermal dissipation requirements if substituting with packages having different thermal resistance characteristics.
